It can be a source of bemusement to those seek the literary inside the Doctor Who universe that the soul of Kit Marlowe has not made an appearance, let alone an impression on the world; for a man to whom English literature would be sorely poorer without having picked up a pen and to whom the world of early espionage and skulduggery would be infinitely more boring to read about, Christopher Marlowe remains intriguingly still persona non grata, not only in the world we inhabit but in the fictional tales that could be wrought.
